SECTION 2: SAFETY PRECAUTIONS
2.01 SECURITY MEASURES
!
WARNING
SERIOUS INJURY OR DEATH may result if welding and cutting equipment is not properly
installed, used, and maintained. Misuse of this equipment and other unsafe practices can
be hazardous. The operator, supervisor, and helper must read and understand the following
safety warnings and instructions before installing or using any welding or cutting equip-
ment, and be aware of the dangers of the welding or cutting process. Training and proper
supervision are important for a safe work place. Keep these instructions for future use.
Additional recommended safety and operating information is referenced in each section.

WARNING
This product contains chemicals, including lead, or otherwise produces chemicals known
to the State of California to cause birth defects and other reproductive harm.
Wash hands
after handling.
ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH
Install and maintain equipment in accordance with the National Electrical Code (NFPA 70) and
local codes. Do not service or repair equipment with power on. Do not operate equipment with
protective insulators or covers removed. Service or repair to equipment must be done by qualified
and/or trained personnel only.
Do not contact electrically live parts. Always wear dry welding gloves that are in good condition.
Aluminized, protective clothing can become part of the electrical path. Keep oxygen cylinders, chains, wires, ropes,
cranes, and hoists away from any part of the electrical path. All ground connections must be checked periodically to
determine if they are mechanically strong, and electrically adequate for the required current. When engaged in AC
welding/cutting under wet conditions or where perspiration is a factor, the use of automatic controls for reducing
the no load voltage is recommended to reduce shock hazards. Accidental contact must be prevented when using
open circuit voltage exceeding 80 volts AC, or 100 volts DC by adequate insulation or other means. When welding
is to be suspended for any length of time, such as during lunch or overnight, all electrode holders and electrodes
should be removed from the electrode holder and the power supply should be turned off to prevent accidental
contact. Keep MIG Guns, electrode holders, Tig torches, Plasma torches, and electrodes away from moisture and
water.
See safety and operating references 1, 2, and 8.
SMOKE, FUMES, AND GASES CAN BE DANGEROUS TO YOUR HEALTH
Ventilation must be adequate to remove smoke, fumes, and gases during operation to protect
operators and others in the area. Vapors of chlorinated solvents can form the toxic gas “Phosgene”
when exposed to ultraviolet radiation from an electric arc. All solvents, degreasers, and potential
sources of these vapors must be removed from the operating area. Use air-supplied respirators if
ventilation is not adequate to remove all fumes and gases. Oxygen supports, and vigorously
accelerates fire and should never be used for ventilation.
See safety and operating references 1, 2, 3, and 4.
